Android LinearLayout : Add border with shadow around a LinearLayout
That's why CardView exists. CardView | Android Developers
It's just a FrameLayout that supports elevation in pre-lollipop devices.
<android.support.v7.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardUseCompatPadding="true"
app:cardElevation="4dp"
app:cardCornerRadius="3dp" >
<!-- put whatever you want -->
</android.support.v7.widget.CardView>
To use this you need to add dependency to build.gradle
:
compile 'com.android.support:cardview-v7:23.+'
I get the best looking results by using a 9 patch graphic.
You can simply create an individual 9 patch graphic by using the following editor: http://inloop.github.io/shadow4android/
Example:
The 9 patch graphic:
The result:
The source:
<LinearLayout
android:layout_width="200dp"
android:layout_height="200dp"
android:orientation="vertical"
android:background="@drawable/my_nine_patch"
Try this..
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#CABBBBBB"/>
<corners android:radius="2dp" />
</shape>
</item>
<item
android:left="0dp"
android:right="0dp"
android:top="0dp"
android:bottom="2dp">
<shape android:shape="rectangle">
<solid android:color="@android:color/white"/>
<corners android:radius="2dp" />
</shape>
</item>
</layer-list>
okay, i know this is way too late. but i had the same requirement. i solved like this
1.First create a xml file (example: border_shadow.xml) in "drawable" folder and copy the below code into it.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<item>
<shape>
<!-- set the shadow color here -->
<stroke
android:width="2dp"
android:color="#7000" />
<!-- setting the thickness of shadow (positive value will give shadow on that side) -->
<padding
android:bottom="2dp"
android:left="2dp"
android:right="-1dp"
android:top="-1dp" />
<corners android:radius="3dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#fff" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>
2.now on the layout where you want the shadow(example: LinearLayout) add this in android:background
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="8dip"
android:background="@drawable/border_shadow"
android:orientation="vertical">
and that worked for me.
